Linux Install -Djava.awt.headless=true

Just installed the server on Ubuntu server which is working here is how to setup the Djava.awt.headless=true where to put it in the java command for anyone having issues maybe putting it in the wrong place

java -Djava.awt.headless=true -jar /home/Blynk/server-0.19.2.jar -dataFolder /home/Blynk -serverConfig /home/Blynk/ &

what does it do?

This option is not necessary. You may skip it.

@Costas -

I have always run my Blynk servers on Pi’s without a display and never needed the command.
